998 1968 Cooper .. the car is not overheating, but water is disappearing. After a bit of google I think the radiator cap maybe the problem .. the radiator neck is an inch from the lip to the shoulder, and the cap is slightly less than 3/4 from the seal to where the cap sits on the lip .. so basically it can't be sealing at all!
I can't see anything on the minispares site which would give me a cap with a longer reach .. any suggestions? thanks
correction .. there is one http://www.minispare...|Back to search
but only rated at 8lbs ...
more accurate measurements would indicate that I have a 3mm gap between the seal and the shoulder
